When adding a parameter to an integration in Demisto, there are numerous types to choose from. Each type will effect the parameter behavior and interaction with the user.

This type of parameter creates a check box in the integration configuration. When the check box is ticked, the value in the integration code would be True, and False otherwise. Example:

Access: demisto.params().get('proxy')

This type of parameter is used for short input parameters, such as server URLs, ports or queries. It creates a small sized text box in the integration configuration.

Access: demisto.params().get('url')

This type of parameter is used for long text inputs, such as certificates. It creates a large sized text box in the integration configuration.

Access: demisto.params().get('cert')

This type of parameters is used for encrypted inputs, such as API tokens. This should not be used for username-password credentials however. It creates a small sized text box with an encrypted text, which would also be stored encrypted in the database.

Access: demisto.params().get('token')

This type of parameter is used for username-password credentials - username as plain text and an encrypted password. It supports retrieving credentials from the Demisto credentials store(more info on the credentials store can be found in the Demisto support portal).

Access:

Username: demisto.params().get('credentials', {}).get('identifier')

Password: demisto.params().get('credentials', {}).get('password')

This type of parameter is used to allow selecting a single input from a list of allowed inputs.

Access: demisto.params().get('log')

This type of parameter is used to allow selecting multiple inputs from a list of allowed inputs.

Access: demisto.params().get('sort')

Once a parameter is set in an integration configuration, it is saved to the Demisto database, so before changing an existing parameter you have to consider the existing values (backward compatibility).
